next in thread | raw e-mail | index | archive | help
Now that I've committed a change which fixes that pesky
lstat() panic in fdesc, I'd like to suggest that it replace the
existing /dev/fd devices and /dev/std{err,in,out}. I've already
got such a setup running on a test box:
Filesystem 1K-blocks Used Avail Capacity Mounted on
/dev/da0s1a 49583 25320 20297 56% /
/dev/da0s1f 804119 697621 42169 94% /usr
/dev/da0s1e 19815 840 17390 5% /var
procfs 4 4 0 100% /proc
fdesc 1 1 0 100% /dev
This fdesc mount is mounted with the `union' option.
And a little demonstration of the 'lightness' of fdesc over
our oodles-of-device-nodes:
$ ls -l 3<&1 4<&1 9<&1
total 0
crw------- 1 chris tty 5, 0 Mar 18 05:02 0
crw------- 1 chris tty 5, 0 Mar 18 05:02 1
crw------- 1 chris tty 5, 0 Mar 18 05:02 2
crw------- 1 chris tty 5, 0 Mar 18 05:02 3
crw------- 1 chris tty 5, 0 Mar 18 05:02 4

dr--r--r-- 2 root wheel 512 Mar 18 04:38 6
dr--r--r-- 2 root wheel 512 Mar 18 04:38 7
crw------- 1 chris tty 5, 0 Mar 18 05:02 9
Compared to our 63 device nodes, I think this is much nicer.
Any of you folks have feedback?
