[Devil-linux-develop] report on ramdisk usage

[Friedrich L. <fl...@fl...>]

Hi!

Just wrote a small script that would unpack each available
package on my Devil-Linux 0.5b6 and calculate the unpacked size.
I have to say that those are not all packages but the ones that 
I selected via "make menuconfig".

package        size [KB]
ARPWATCH         154
CRON              53
DDUP              22
FREESWAN        1052
IPROUTE2         270
ISC_BIND        2771
ISC_BIND_UTILS  2547
ISC_DHCP        1723
JFTPGW           150
JOE              210
LVM              810
NTP             1516
OPENSSH         1919
OPENSSL_BIN     1102
PERL           16165
POPTOP            54
POSTFIX         4392
PPP              278
PPTP_CLIENT       46
SQUID           2180
TCPDUMP         1318
UCD_SNMP        2609
WGET             182
             ========
SUM [KB]       41523

To complement the picture we need the ramdisk usage of the 
BASE-System, which is (at least for my config) 16132 KB.

Let's say that the BASE-System and an extended config needs
18000 KB.

So for a full install of the packages above the ramdisk
needs to be at least of the size of:
  59523 KB = approx. 58,2 MB

I would suggest using at least 96 MB of ram for this full install. 
Which would leave approx. 32 MB for running all the services.


I would also suggest to create files on the cd that reflect the
size of the available packages.
eg. (as seen from the running system) /cdrom/packages/CRON.size
with the content "53\n". (for the value see list above)

So a script could be written that loads /etc/sysconfig/software,
and based on those settings, calculates the needed ramdisk size
and would also give recommendations on the amount of ram that
needs to be installed.


PS: If you want a copy of this script mail me. 
If you'd want to run this script don't forget to configure your
harddisk support because it's advisable to run this on a mounted 
partition.

PPS: I'm thinking about adjusting the ramdisk size on the
amount of installed memory. But no solution yet.
