Re: [Bsdrp-devel] PATCH: Cross compile BSDRP for EdgeRouter Lite mips64

[Cesar F. <ces...@gm...>]

I can try a better implementation if you want to integrate it.
With arm/mips the scripts may need a SUB_ARCH since they can have some
vendor specific info.

About the labels on a x86 to big endian
makefs -B big -o label=XXX then dd to a md the label get lost ... no clue
why.
If I just copy the makefs image to a partition and mount it on mips labels
are ok.

As for the loader I was able to do almost all I needed without it.
mount.conf can be changed to tell which image to boot.
nvram2env worked great as a simple replacement for loader.conf read
only tunable.
