[OSR-devel] /etc/mtab

[Gordan B. <go...@bo...>]

Is there a particular functional reason why /etc/mtab should be 
symlinked to /proc/mounts instead of /cdsl.local/etc/mtab?

The reason I ask two-fold:

1) I'm not sure if having it symlinked to /proc/mounts confuses the 
process of unmounting the file systems in the shared root during 
shutdown. /proc/mounts shows all mounted file systems, including paths 
that aren't mounted in the OSR root (e.g. /mnt/tmproot for the glfs 
backing fs is mounted only in the initroot, but still shows up in 
/proc/mounts).

2) It seems to interfere with the checks to see whether a bind-mount is 
already mounted. Under OSR, I'm seeing all bind-mounts in fstab getting 
mounted twice, once when mounting local file systems, and once when 
mounting "other" file systems.

Is anything likely to break if /etc/mtab is symlinked to 
/cdsl.local/etc/mtab?
