Hallo!
I have a "logocal based" :-) problem with devfs.
What is there:
/dev as mountpoint for devfs
an entry in fstab to mount devfs
and devfsd started as the first of all before any other things done
in any bootscript.
This works for most cases. But: The mixer and pcm devices of the alsa-
sound driver I use cannot be accessed that way. The configure script
of devfsd tells devfsd to make some old fashioned symlinks from the
alsa devices (the alsa driver supports devfs) to the "old" device hierachy
as used by some programs not aware of devfs. So nice so fine. The "real"
alsa devices are of the correct permissions/modes: (rw-)*.
Until now I thought, symlinks under linux does not have any permissions/modes
itsself, they get them from their targets they link to.
Not under devfs! The symlinks show a (r-x)* mode.
Therefore the pcm and mixer devices are not accessible for writing.
Same *seems* to be relevant to the devpts.
If I compile a kernel with devfs support and no extra devpts support -- as
said in the readmes for devfs -- I cannot use gpg via mew via xemacs: The
passport dialog is not fetched by xemacs, instead it appears on the terminal
from where xemacs was started (or in the depth of the windowmanager, if
started via menu). Input of the passphrase is impossible in either case.
So, what I am doing wrong?
Different manual chmod/chown attacks on the devices in questions and via the
cnf-file of devfsd failed.
KEEP HACKING!
