It avoids having to remember to type -w on the
poudriere bulk command line.

Both cause a crash in the jail to produce a .txz
(or other tar format) of the /wrkdirs/ directory
tree that it was using when the crash happened.

The can later be extracted and the contents examined
for getting evidence about the problem.

No.

Individual builders (jobs) never restart in the
middle: always at the beginning. But prior
completed builders/jobs are not rerun unless
something changed to cause such.

From man poudriere-bulk :

     -w       Save WRKDIR on build failure.  The WRKDIR will be tarred up into
              ${POUDRIERE_DATA}/wrkdirs.

I will note that the WRKDIR concept is not specific to
poudriere but to all the ports infrastructure. From
man ports :

     WRKDIRPREFIX      Where to create any temporary files.  Useful if
                       PORTSDIR is read-only (perhaps mounted from a CD-ROM).

. . .

     SU_CMD            Command used to elevate privilege to configure and
                       install a port.  The unprivileged user must have write
                       access to WRKDIRPREFIX and DISTDIR.  The default is
                       ā€˜/usr/bin/su root -cā€™.  Many users set it to
                       ā€˜/usr/local/bin/sudo -E sh -cā€™ for convenience.


SIDE NOTE:

main has commits today for avoiding the rust build failures.
