+# man bash covers everything comprehensively of course.  i use ~/.bash_profile
+# to source bashrc, and .profile just echos that the normal bash startup process
+# is not happening.  I don't source bashrc in posix mode based on debian's
+# default, and posix mode is quirky, doesn't seem worth figuring it out This
+# setup ensures no distro can override anything, as they occasionally do things
+# I don't like. For example, debian's root .profile spamms with "mesg n"when
+# there is no tty. The mesg n ensures the terminal is not writable by other
+# users, but it is that way without the mesg n, and google search, and debian
+# wiki search, /usr/share/doc search gives no justification for it, and it's not
+# in fedora, so I'm pretty confident that it is useless redundant security, plus
+# it is purposefully in a user startup file, not a system one, so intended for
+# the user to change.
