[Vectorlinux-devel] vl-hot mount arguments for different FS types

[Jose J. R. <jo...@gm...>]

I need feedback on the correct mount arguments for the different FS
types. So far I've discussed, tested and tweaked the following:
ReiseFS, NTFS, FAT12, FAT16 and FAT32. I don't have other FS type
partitions to test with, nor available hardware to repartition for
testing (I've used my working pendrive and USB hdd, or feedback in the
Forum). Here are the current mount arguments used by vl-hot. I already
know ext2 and ext3 are wrong, as feedback from Kocil tonight suggests.
Also, what other FS types do you think should be implemented?:


# Mount options:
USB_USER=3Droot
USB_GROUP=3Dusers
USB_UMASK=3D0111
USB_DMASK=3D0000
# consider adding the noatime option to save writes to flash mem:
MOUNTSYNC=3D"noatime"
# MOUNTSYNC=3D"sync,dirsync"=09=09#too friggin' slow!


function chooseMountOptions {
=09case $fsType in

=09;;
   *)
=09=09MOUNT_OPTIONS=3D"UNKNOWN"
=09=09fsMountTypeArg=3D"auto"
=09;;
=09esac
}


Note: I changed the NTFS mounting from ro to rw tonight by request from Vec=
7.

No new FS types, just some notes... for vfat file systems:
1) I use options fmask=3D111,dmask=3D000 - otherwise all files look as exec=
utable.
2) I think charsets should be configurable: you use
iocharset=3Diso8859-15,utf8, I use iocharset=3Dcp1251,codepage=3D866. Or
these options could be obtained authomatically: "iocharset" could be
obtained from the system locale settings, and "codepage" could be
defined by "iocharset" via some mapping of encodings (a subset of it
would be Windows "ANSI to OEM" mapping).

This is different from umask=3D0111 and dmask=3D0000 that vl-hot currently
uses? Sorry, but file masks are still a sort of grey area for me.

Very good point. I'd need some help with this though. Another way
could be the through configuration interface I always intended to make
for vl-hot, but time is so short....

For me too ;) Yes, you are right, "umask=3D0111,dmask=3D0000" yields the
same result.

I am ready to help.
Also I would like VL-Live to generate fstab with encoding options,
depending of the chosen locale - that could be a simple dialog/Xdialog
dialog during startup, I saw such dialogs in some live distros.
So, I'll try to write a script and maybe also a small C program, which
will define two env. variables for use in fstab, say FSTAB_IOCHARSET
and FSTAB_CODEPAGE.
BTW the codepage can also be used for automatic setup of ncpfs (Novell
Netware) and smbfs (Window Network).

Here is a first draft of my script, which needs additional charset
mapping entries. At home I have some additional info about AnsiToOem
mapping.

--------------------- BEGIN -----------------------
#!/bin/sh

export FSTAB_IOCHARSET=3D`locale charmap | tr A-Z a-z`
case "$FSTAB_IOCHARSET" in
    "iso-8859-1" | "ansi_x3.4-1968" | "cp1252" )
        FSTAB_CODEPAGE=3D"850";; # Latin 1
    "iso-8859-2" | "cp1250" )
        FSTAB_CODEPAGE=3D"852";; # Latin 2
    "iso-8859-5" | "cp1251" | "koi8-r" | "koi8-u" )
        FSTAB_CODEPAGE=3D"866";; # Cyrillic
    *)
        FSTAB_CODEPAGE=3D"437";;
esac
export FSTAB_IOCHARSET FSTAB_CODEPAGE
echo "iocharset=3D$FSTAB_IOCHARSET,codepage=3D$FSTAB_CODEPAGE"
--------------------- END -----------------------

Okay, now I am pretty sure about the rest of charset mappings, assume
this is a beta version:
--------------------- BEGIN -----------------------
#!/bin/sh

export FSTAB_IOCHARSET=3D`locale charmap | tr A-Z a-z`
case "$FSTAB_IOCHARSET" in
    "iso-8859-1" | "iso-8859-15" | "ansi_x3.4-1968" | "cp1252" )
        FSTAB_CODEPAGE=3D"850";; # Latin-1 & Latin-9
    "iso-8859-2" | "cp1250" )
        FSTAB_CODEPAGE=3D"852";; # Latin-2
    "iso-8859-5" | "cp1251" | "koi8-r" | "koi8-u" )
        FSTAB_CODEPAGE=3D"866";; # Cyrillic
    "iso-8859-6" | "cp1250" )
        FSTAB_CODEPAGE=3D"864";; # Arabic
    "iso-8859-7" )
        FSTAB_CODEPAGE=3D"737";; # Greek
    "iso-8859-8" )
        FSTAB_CODEPAGE=3D"862";; # Hebrew
    "iso-8859-9" | "cp1254" )
        FSTAB_CODEPAGE=3D"857";; # Turkish
    "iso-8859-13" | "cp1257" )
        FSTAB_CODEPAGE=3D"775";; # Baltic
    *)
        FSTAB_CODEPAGE=3D"437";;
esac
export FSTAB_IOCHARSET FSTAB_CODEPAGE
echo "iocharset=3D$FSTAB_IOCHARSET,codepage=3D$FSTAB_CODEPAGE"
--------------------- END -----------------------

However if the current encoding is UTF-8, then it's impossible to
define FAT codepage automatically :(
In this case it should be configured manually.

Solution exists! We can check $LANG in this case!

I decided to use codepade 850 by default, because I don't see any
drawbacks of this decision. Does anybody see them?

Sorry for too much letters from me today.
I've just understood how to simplify the script: the FAT codepage can
be determined by $LANG in all cases.
