This addresses a regression introduced by#224. POSIX sh does notdefine arguments to the exec built-in, resulting in an error whenusing 'exec -a' to set the process name (argv[0]).This change executes /bin/bash instead of sh, and also changesto use 'exec -l', which automatically handles the hyphen prefixrequired to trigger login shell behavior.This also explicitly runs /bin/sh, aligning the behavior of"coder sh" and the frontend Terminal application.

sh
does not define arguments to theexec
built-in, resulting in an error when usingexec -a
to set the process name (argv[0]
).This change executes
/bin/bash
instead ofsh
, and also changes to useexec -l
, which automatically handles the hyphen prefix required to trigger login shell behavior.This also explicitly runs
/bin/sh
, aligning the behavior ofcoder sh
and the frontend Terminal application.Tested this using Arch Linux (enterprise-dev image) as well as the base Debian image from DockerHub.
