I've not tried the documented upgrade process
believe there's a serious problem here having to
do with recommending that a purge takes place
_before_ system reboot.
1st, the old kernel, although upgraded, will still
(AFICT) be running. Trying to purge a running kernel
is ungood. The purge of the kernel must be delayed
until after reboot.
2nd, I believe the following warning should
be included in the docs:
Some packages, notably PostgreSQL (and the kernel),
leave the bulk of their executables installed and
running to facilitate upgrade to the newly installed
version. These packages must NOT be purged until
after following the upgrade instructions found
Purging such packages before migrating to the package's
new version can introduce substantial complications.
The phrase "(and the kernel)" could be modified to
"(and the kernel, as noted)" or something else depending
on how the kernel purge is addressed.
Note that the kernel package warns the user when he
tries to purge a running kernel. The postgres package,
last I checked, does not warn in similar circumstances.
I'd be nice if postgres had such a check, and perhaps
if there was policy to cover any other such cases.
