The s6-frontend-alias-chpst program
by rewriting itself into a command line made of idiomatic
chainloading s6 commands.

When s6-frontend has been configured with the
--enable-aliases-runit option, the
s6-frontend-alias-chpst program is built, and at installation
time, a chpst symbolic link is created, pointing to it.
s6-frontend-alias-chpst implements most of the functionality of
chpst, as closely as
possible. It does so by rewriting itself into a command line that may
invoke one or more of the following programs:
- When the -v option is given,
s6-frontend-alias-chpst prints an informational
message to stderr, showing the entire command line it is going to execute into.
- s6-frontend-alias-chpst is a convenience program, written
so that runit users can keep using chpst while learning the
corresponding idiomatic s6 commands. However, it is not an "official"
interface. chpst acts as a big toolbox, whereas s6 prefers the
"one function = one tool" philosophy. It is recommended that runit users
who are new to s6 use the -v option to see how their chpst
invocation translates into s6 parlance.
- Some chpst -u invocations do not translate perfectly
because s6 uses a slightly different model of acquiring user and group
This should not prevent chpst from working.
