Re: native Linux userland in Windows 10

Warren Young scripsit:

No.  It treats a leading double slash as a single slash, despite the Posix
permission to do otherwise, and treats a non-leading double slash as an
error, despite the Posix requirement not to do that.  (I have reported
this bug to Feedback Hub.)  Thus, even though "cat ./dogs" works,
"cat .//dogs" returns ENOENT.

Actually, it does do privilege separation independent of Windows.
I added cowan as a user with useradd -m, and I just do "su - cowan" by
hand as the first thing when the initial bash starts up.  All is well;
I get EPERM when I try to write into /bin.

you are on a well-traveled road of spiritual inquiry.  If you are
absolutely sure you are in hell, however, then you must be on the Cross
