CONFIG_RAMFS in 2.4.19-pre7-ac2 ???

CONFIG_RAMFS in 2.4.19-pre7-ac2 ???

[Roy Sigurd Karlsbakk]

hi

After upgrading to 2.4.19-pre7-ac2, I can't get CONFIG_RAMFS into the 
kernel. And - diskless clients seem to work better with it, as they can't 
get a rootfs without it.

Any ideas?

Gee, I hope CONFIG_RAMFS isn't going away.  I need it to
do loopback mounts of cramfs on an embedded system that
uses tmpfs as its main filesystem.  (tmpfs doesn't support
loopback mounts.)

The release notes say that ramfs needs a bit of work, 
so if you found ramfs was broken, maybe that's why.

I beleive it's there by default after -pre7, but somehow it doesn't work

CONFIG_RAMFS is probably going away, but that doesn't mean ramfs is
going away.  At least in Linux 2.5 ramfs will end up being required
core code.

According to what I was told by a guy at #KernelNewbies, CONFIG_RAMFS 
isn't there in (menu|x)?config after -pre7, but in by default. problem is 
- it doesn't work
