I have run Arch on several filesystems and I've been lucky I guess.
Currently on this box, I have ext3, ext4 and reiser (old SuSE 10.0 partition).
This box has been running since mid-2009 and updates are usually weekly
(sometimes I go a couple of weeks if I can't risk a break due to workload) I
have not had any of the mount ro weirdness even after several multi-gigabyte
updates. The current partitions I have are:
/dev/sdc5 on / type ext3 (rw,relatime,data=ordered)
/dev/sdc7 on /home type ext4 (rw,relatime,data=ordered)
/dev/sda2 on /mnt/pv type reiserfs (rw,relatime)
/dev/sdb2 on /mnt/win type fuseblk
I don't know what is doing it in your case, but it seems like we should be
able to figure out where mount ro/rw logic for the resides (I picture
something like the following buried somewhere):
if [conditional]; then
mount -o rw [whatever]
mount -o ro [whatever]
I suspect this may be complicated by the fact that mounting (or remounting)
takes place in several different places/processes during the boot. Anybody
familiar with this off-hand or any idea where Pete might look to rule-in or
rule-out the different parts of boot that could effect this? Sorry I don't
have more, I just haven't had the need to dissect the boot mount process to
that level before...
I guess you are just lucky :)
