This fixes a bug whereby /var/log/wtmp would never be created, and thus
accounting information would be lost.
* gnu/services.scm (activation-script): Create /var/log/wtmp.
* gnu/tests/base.scm (run-basic-test)["wtmp entry"]: New test.
This fixes a bug whereby /var/run/utmpx would never be created, and thus
accounting information would be missing.
* gnu/services.scm (activation-script): Create /var/run/utmpx.
* gnu/tests/base.scm (run-basic-test)["utmpx entry"]: New test.
* gnu/services.scm: Export service-extension-target and
service-extension-compute. This allows for greater extensiblity of services
by enabling service extensions to be wrapped. For example, the parameters
passed to the compute function can be modified, or the return value of the
compute function can be modified.

This allows using (PACKAGE OUTPUT) in the packages field.
Reported by Jan Nieuwenhuizen <janneke@gnu.org>.
* gnu/services.scm (packages->profile-entry): Use 'packages->manifest'.
Before that, specifying an invalid timezone in 'operating-system' would
lead to a dangling symlink in the 'etc' directory, which in turn would
lead to a kernel panic at boot time.
Reported by pizzaiolo on #guix.

undetected.
