But having a separate /usr partition +# hasn't really made sense for a long time and leads to all kinds of +# bugs these days. We're going to make /etc/localtime a symlink just +# like everyone else does so that programs that expect it to be a link +# can fetch the timezone without requiring any special patches. +# If you insist on making /usr a separate partition, you might want to +# put the pointed-to directories and timezone file in your empty /usr +# directory so that it is available before the real /usr is mounted. +# Still not recommended though. + +# In a special case, we will handle the removal of the US/Pacific-New +# timezone. A bit of background information on this: +# +# "US/Pacific-New' stands for 'Pacific Presidential Election Time', +# which was passed by the House in April 1989 but never signed into law. +# In presidential election years, this rule would have delayed the +# PDT-to-PST switchover until after the election, to lessen the effect +# of broadcast news election projections on last-minute west-coast +# voters. " +# +# In nearly all cases, a machine that uses the US/Pacific-New timezone +# has chosen it by mistake. In 2016, having this as the system timezone +# actually led to clock errors, and after that it was decided that the +# timezone (only of historical interest anyway) should be removed from +# the timezone database. +# +# If we see that the machine's localtime-copied-from symlink is pointing +# to US/Pacific-New, change it to point to US/Pacific instead. +if [ "$(/bin/ls -l etc/localtime-copied-from 2> /dev/null | rev | cut -f 1,2 -d / | rev)" = "US/Pacific-New" ]; then + ( cd etc ; rm -rf localtime-copied-from ) + ( cd etc ; ln -sf /usr/share/zoneinfo/US/Pacific localtime-copied-from ) +fi +# Same with any /etc/localtime symlink: +if [ -L etc/localtime ]; then + if [ "$(/bin/ls -l etc/localtime 2> /dev/null | rev | cut -f 1,2 -d / | rev)" = "US/Pacific-New" ]; then + ( cd etc ; rm -rf localtime ) + ( cd etc ; ln -sf /usr/share/zoneinfo/US/Pacific localtime ) + fi +fi + +# If we already have a localtime-copied-from symlink, move it over as the +# /etc/localtime symlink: +if [ -L etc/localtime-copied-from ]; then + rm -f etc/localtime + mv etc/localtime-copied-from etc/localtime +fi + +# Add the default timezone in /etc, if none exists: +if [ ! -r etc/localtime ]; then + ( cd etc ; rm -rf localtime localtime-copied-from ) + ( cd etc ; ln -sf /usr/share/zoneinfo/Factory localtime-copied-from ) +fi + +# Add a link to the timeconfig script in /usr/share/zoneinfo: +( cd usr/share/zoneinfo ; rm -rf timeconfig ) +( cd usr/share/zoneinfo ; ln -sf /usr/sbin/timeconfig timeconfig ) +### Make the rest of the symbolic links in the zoneinfo database: |
