References: <3BCEAD9C DOT B2A273B1 AT cern DOT ch> <3BCF1A01 DOT 34CB395F AT cportcorp DOT com> Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit This is to follow up on my problem where I have cygdrive prefix set to `/', both system and user setting, but $PATH and other env vars are initialised to /cygdrive/x. This happens only when the process (inetd or sshd) is started as a service under the system account. Under the same remote session mount reports the expected values (`/'). The extra /cygdrive prefixes causes problems with the $PATH: cygwin thinks those /cygdrive//... directories don't exist (which is consistent with mount output). After some further testing: - sshd -d didn't seem to print any useful information - sshd started from cygwin/bash command line on my own account does not have this problem - I managed to get the sshd-as-service to run under strace; beginning of the output is attached below. From the strace output, cygwin seems to happily use the /cygdrive prefix instead of `/'. I am not sure how I can debug this further -- experts, please help. I am happy to debug this under gdb if some kind soul can explain to me how do I do that in the service conditions... Is there a way to get more output from strace? Any other debugging ideas? I can provide the strace outputs both with and without /cygdrive prefix set if someone thinks that will be useful.
