x86_64 Intel(R) Core(TM) i7-4700MQ CPU @ 2.40GHz GenuineIntel GNU/Linux
Machine Type: x86_64-pc-linux-gnu
Bash Version: 4.3
Patch Level: 42
Release Status: release
Description:
In a bash session where the MAIL variable is not explicitly set, the
MAIL variable might be auto-set through a compile time definition of
DEFAULT_MAIL_DIRECTORY. There is no method (no method I know of) to find about
about these compile time definitions and / or configuration flags.
To find out about this bevaiour I needed to read the source code and
finally found this line in CHANGES:
hhh. Improved the mail checking code so it won't check (and possibly
cause an
NFS file system mount) until MAILPATH or MAIL is given a value --
there
is no default if DEFAULT_MAIL_DIRECTORY is not defined at compile
time.
Repeat-By:
Install bash and remove all occurences of MAIL= or similar from the
several profile and rc files.
Fix:
Please describe the dependency of the MAIL variables on the manual
page. If you manage to do so, add the value of DEFAULT_MAIL_DIRECTORY and it's
effects in the generated manual pages.
