[Buildroot] proc mount needed in both inittab and fstab?

[Buildroot] proc mount needed in both inittab and fstab?

[Danomi Manchego]

Hi, quick question: I noticed that the skeleton/etc/inittab has:

# Startup the system
null::sysinit:/bin/mount -t proc proc /proc
null::sysinit:/bin/mount -o remount,rw / # REMOUNT_ROOTFS_RW
null::sysinit:/bin/mkdir -p /dev/pts
null::sysinit:/bin/mkdir -p /dev/shm
null::sysinit:/bin/mount -a
...

and that fstab has:

# <file system> <mount pt>     <type> <options>         <dump> <pass>
/dev/root       /              ext2 rw,noauto         0      1
proc /proc        proc     defaults   0  0
...

I was wondering - is the /proc mount in inittab needed, since there is a
corresponding line in fstab?

Thanks in advance,
Danomi -

I /think/ yes, because I believe 'mount -a' needs /proc/mounts to be
available in order to work properly.
