true. but adding the required code to s6-svscan as
daemontools-encore did would obsolete execline at least for
this purpose entirely (which is a good thing IMO).
it should not be to much of an effort to add this functionality
to s6-svscan (and perp(d) for that).

definitely true. but this is non intended use, so don't do it,
it was not recommended in the docs in any way.
(btw: this could be clarified in the doco)
still a pretty artificial consideration.

not in the case of daemontools-encore which you were referring to.

indeed, especially excluding any read-write fs access requirements.

yes true, but IMO process #1 should not require read-write access
to any fs for proper operation. for subprocesses this is not a problem,
