| |
| Global changes |
| -------------- |
| |
| Various pages |
| Michael Kerrisk |
| Use .EX/.EE for EXAMPLE programs |
| |
| Various pages |
| Michael Kerrisk |
| Use consistent markup for code snippets |
| Change .nf/.fi to .EX/.EE |
| |
| Various pages |
| Michael Kerrisk |
| Use consistent markup for code snippets |
| The preferred form is |
| |
| .PP/.IP |
| .in +4n |
| .EX |
| <code> |
| .EE |
| .in |
| .PP/.IP |
| |
| Various pages |
| Michael Kerrisk |
| Formatting fix: replace blank lines with .PP/.IP |
| Blank lines shouldn't generally appear in *roff source (other |
| than in code examples), since they create large vertical |
| spaces between text blocks. |

| triggering the mount. |
| |

| |
| umount.2 |
| NeilBrown |
| Revise MNT_FORCE description |
| MNT_FORCE does not allow a busy filesystem to be unmounted. Only |
| MNT_DETACH allows that. MNT_FORCE only tries to abort pending |

| Also, the pow10() functions are no longer supported by glibc, |
| starting with version 2.27. |

| host.conf.5 |
| Michael Kerrisk |
| Add cross-reference to hosts(5) |
| |
| locale.5 |
| Marko Myllynen |
| Refer to existing locales for encoding details |
| Since I don't think it would make sense to try to have different |
| explanation for each glibc version on the locale(5) man page, I'm |
| proposing that we apply the below patch so that we refer to |
| existing locale definition files in general and not spell out the |
| exact format or any certain locale as a definitive guideline. |
| |
| nologin.5 |
| Michael Kerrisk |
| Add a sentence explaining why nologin is useful |
| |
| proc.5 |

| Paul Eggert |
| Sync from tzdb upstream |
| This makes tzfile.5 a copy of the tzdb version, except that the |
| tzdb version's first line is replaced by man-pages boilerplate. |
| The new version documents version 3 format, among other things. |
| Also, it removes the "Summary of the timezone information file |
| format" section, which should no longer be needed due to |
| improvements in the the part of the man page. |
| |
| capabilities.7 |
| Michael Kerrisk |
| Note semantics for a program that is set-UID-root and has capabilities |
| Note semantics for a program that is both set-user-ID-root and has |

| security/keys for some reason. |

| Expand the guidance on formatting code snippets |
| |
| netlink.7 |
