Subject: Make expect value in test 62 depend on page size
https://buildd.debian.org/status/fetch.php?pkg=logrotate&arch=powerpc&ver=3.11.0-0.1~exp2&stamp=1483609625
https://buildd.debian.org/status/fetch.php?pkg=logrotate&arch=ppc64el&ver=3.11.0-0.1~exp2&stamp=1483609707
The Debian buildds, at least those running ppc64el (they also build
for powerpc) put the source tree into a tmpfs. A tmpfs allocates
memory per page, and with an unusually huge page size of 64Ki, the
two pages needed for a sparse file with some content as created in
test 62, 128Ki are actually allocated - which is more than the limit
of 100 in the test.
So get the actual pagesize and raise the limits if it's 32Ki or
more. The second limit is wild-guessed, in the failing test the
value was 10304 (= 131 pages).
On a 4Ki-page system (amd64), the observed values were 8 (= two
pages), and 12 (= three pages).
Reproducer:
printf zero > test.log ; truncate -s 10M test.log ; echo x >> test.log ; du test.log
