+.\"=====================================================================
+.SH NOTES
+When called by root with no arguments, \fBmktexlsr\fP in Debian ignores
+TEXMF trees under \fI$HOME\fP. This is to avoid creating undesirable files
+such as \fI/root/texmf/ls-R\fP when doing usual maintainance (it is generally
+a bad idea to work with TeX as root, therefore having a file such as
+\fI/root/texmf/ls-R\fP in the first place is rather pointless). If you really
+want to update the ls-R databases for such TEXMF trees, simply list them
+explicitely on the command-line.
