On 11/12/05 21:02 Dinesh Nair said the following:
how does one specify a read/write mount of mfsroot in 6.0 in the
bootloader ?
apparently, the behaviour of vfs_mountroot_try() has changed in 6.0.
previously, if the root filesystem was mounted from a memory disk, as would
be the case with an mfsroot.gz, it would be mounted R/W while other fs
types would be mounted R/O before /etc/rc scripts upgraded the mount to
R/W. however, in 6.0, all root filesystems are mounted R/O.
the following patch mounts all root filesystems R/W. it's a quick and dirty
fix however, for a cleaner fix would be to duplicate 5.x behaviour of only
mounting memory disks R/W and other disks R/O. the kernel needs to be
rebuilt for this patch to take effect.
is there enough interest in having memory root file systems mounted R/W at
boot ? if there is, i could put in a little bit more effort into
duplicating 5.x behaviour on this and submitting it as a PR to 6.0.
