#109 mount --pass-fd deprecated

[Federico Reghenzani]

When user login and consequently mounts an encrypted partition, there is an error from mount:

(mount.c:72): mount: --pass-fd is no longer supported

However the partition mounts correctly.

pam_mount 2.13.5
util-linux 2.23.1

--pass-fd removal started with a deprecation, back in 2012:
http://git.kernel.org/cgit/utils/util-linux/util-linux.git/commit/?id=5cf05c71472bf7230075cbdcd5cd6eb12b1d3654

I initially though about --pass-fd being useful with keyfile=/dev/stdin but it seems that not.

My pam_mount setup (with crypt, I got the --pass-fd warning on each login) just broke completely on Linux 3.14. Maybe support for that option got completely removed in the latest kernel? (I still get the same warning though, so maybe it’s another reason.)

[Lucas Werkmeister]

Well, I tried to bisect the Linux kernel between 3.13 and 3.14, and somewhere along the bug vanished, and pam_mount works again – I assume it was a bad config choice (during the bisect I mostly used the default values). Nevermind.
