Package: installation-reports
Severity: normal
Dear Maintainer,
I installed debain with encrypted hard disk. The /tmp directory is mounted to
a separate partition with a random key. In /etc/crypttab the line
sda3_crypt /dev/sda3 /dev/urandom cipher=aes-xts-plain64,size=256,tmp
was generated, in /etc/fstab the line
/dev/mapper/sda3_crypt /tmp ext2 defaults 0 2
was generated. During boot I got the message
Mounting local filesystems...mount: wrong fs type, bad option, bad
superblock on /dev/mapper/sda3_crypt,
missing codepage or helper program, or other error
[...]
And indeed, the /tmp file system was not mounted. According to crypttab(5), I
changed the corresponding line in /etc/crypttab to
sda3_crypt /dev/sda3 /dev/urandom cipher=aes-xts-plain64,size=256,tmp=ext2
Now the /tmp file system is mounted on boot as expected.
It seems to me that the original crypttab entry is either invalid (as the
option 'tmp' needs to be followed by '=<tmpfs>') or the default file system for
tmp is not ext2.
For the sake of completeness I append /etc/crypttab and /etc/fstab. The only
manual change I have made is the above mentioned line in crypttab.
Thank you for the (otherwise) really great automated installation process.
Sincerely
Lars
