Currently we request a login shell by passing the -l argument
to the shell. This is either hardcoded, or required to be
specified by the user in the virt-login-shell.conf file.
The standard way for login programs to request a shell run
as a login shell is to modify the argv passed to execve()
so that argv[0] contains the relative shell filename
prefixed with a zero. eg instead of doing
const char **shellargs = ["/bin/bash", "-l", NULL];
execve(shellargs[0], shellargs, env);
We should be doing
const char **shellargs = ["-bash", NULL];
execve("/bin/bash", shellargs, env);

# Master configuration file for the virt-login-shell program.

# All settings described here are optional - if omitted, sensible

# defaults are used.

|
|
# By default, virt-login-shell will connect you to a container running
|
|
# with the /bin/sh program. Modify the shell variable if you want your
|
|
# users to run a different shell or a setup container when joining a
|
|
# container. Shell commands must be a list of commands/options separated by
|
|
# comma and delimited by square brackets. Defaults to: /bin/sh -l.
|
|
# Modify and uncomment the following to modify the login shell.
|
|
#
|
|
# shell = [ "/bin/bash" ]
|
|
#
|
|
# Note there is no need to pass a '--login' / '-l' argument since
|
|
# virt-login-shell will always request a login shell

# The list of names support glob syntax.
